Application filed September the *peciticzition.

h invention relnlics to iniprovcmciits in snti rid devices and the oh ect oi the 1nventicn is to provide :1. simple and inexpensive attachment which may be quickly and conveniently mounted and dismounted upon it vehicle Wheel, and s further object is to provide such or device which, when mounted, cannot accidentally become disenp; end, and which Will permit su'llicicnt loosencss of lit upon the tire so that the wear will he reduced. to s ininin'ium.

My invention consists essentially o'l ft rigid bracket adopted to ensure the Whe l telly betvveen adjacent spokes, a chain secured to one end of the bracket and psssi over the tire, and means for securing the other end of the chain to the oppoc end of the bracket, so that the bracket and chain are thus Secured in position upon the Wheel, all as hereinafter more particularly described and illustrated in the accompanying drawings in which Fig. 1 is a transverse section through e portion out o vehicle Wheel, showing my invention mounted thereon a rigid bracket and it looking finger carried tl'iereby, being? shown in central longitudinal section and u chain. used. in my invention beinp; shown in'oken away in terniedistely.

Fig. 2 is a. top plan view oi' the bracket showing the connection thereto at the two end links oi? the chain.

In the drawings like characters of reference indicate corresponding ports in the di'llerent views.

1 is the telly of s vehicle Wheel upon Which is carried, otter the usual insnner, the tire 2.

is one of the spokes oi the Wheel.

1 indicates collectively my improved dcvice, Which comprises the rigid bracket 5, the locking lever 6, and the Clitt'lll 7.

The bracket 5 is provided on its outer side with n transverse recess 53 situated. l11b611116* dintely of the length. of the brecket.

The inner side of the bracket provided with a longitudinal recess 9 extending the entire length of the bracket, and also adjacent to one end with an outwardly extending transverse recess 10, which latter recess forms the lugs 11 on the sides of the bracket at that end.

The locking lever (B is hingedly connected at one end to the bracket 5 by the pin 12, which is mounted in the lugs 11. I

13 is an inwardly directed hook formed on the lever 6 adjacent to the hinge connection 12.

The lever 6 engages within the longitu- (llllttl recess 9 in the bracket and, when in the locked position ("full lines in Fig. 1) the hook 113 registers with the top of the transverse recess 10.

One end link 14: of the chain 7 is connected to the bracket within the recess 9 bv means of the pin 15.

lhe other end link 16 of the chain is adapted to be passed over the opposite end oi the bracket 5 and also over the lever s when in the dotted position at A in Fig. 1.

.Vhen in the locked position (see Fig. 1 full lines) the link 16 engages Within the transverse recess 10 and under the hook 13. p The operation of my invention is as folions.

The device is mounted by simply placing, the bracket 5 transversely upon the Wheel between adjacent spokes, so that the inner portion oi. the telly 1 engages Within the transverse recess 8.

The chain 7 is then passed. over the tire and the locking lever (3 is passed through the end link 16, the lever being in the dot ted position A. in Fig. 1.

This link 16 is then passed onto the end of the bracket and the lever 6 moved from its imlocked position to its locked position.

Iln the locked position the link 16 lies within the trsn verse recess 10 and also Within the hooked portion 13 of the lever.

lfn this position it will be evident that the device cannot become accidentally disen- ,Q'ilgZR-Hl, since the normal pull of the chain will be outwardly upon the hook 13, thus serving to maintain the device locked in position upon the Wheel.

The device is disengaged by simply press ing' the lever G into its unlocked position and removing the end link 16 from engageinent therewith.

it is to be noted that any desired number of my devices may be used n a. vehicle Wheel and that, as each set is an entirely independent unit, any breakage which may occur to one will not in any way effect the remaining sets. I

What I claim as my invention is:

1. A device of the class described comprising, a rigid bracket provided with a longitudinal recess in its inner side, a lever hingedly connected at one end to one end of the bracket'and engageable within saidrecess, an inwardly directed hook formed on the lever adjacent to its hinge point, the inner side of the bracket provided with a further transverse recess adjacent to the hook on the lever, a chain, one end link of the chain secured to the bracket at the end remote from the hinge'connection of the lever, the other end link of the chain adapted to pass over the opposite end of the bracket and the lever and to engage within the transverse recess in the bracket and also within the hook.

2. A device of the class described comprising, a rigid bracket provided with a longitudinal recess in its inner side, a lever hingedly connected at one end to one end of the bracket and engageable within said recess, an inwardly directed hook formed on the lever adjacent to its hin oint, the inner side of the bracket provide with a turther transverse recess adjacent to the hook on the lever, a chain, one end link of the chain secured to the bracket at the end remote from the hinge connection of the lever, the other end link of the chain adapted to pass over the opposite end of the bracket and the lever and to engage within the transverse recess in the bracket and also within the hook, the bracket provided intermediately of its length with a transverse recess in its outer side.
